RE: [EXTERNAL] Re: GI version 18 or 19c?

Thanks everyone. Just found out that 19c wont support the standard ed (that’s what we have for this project). It means either we give up on RAC or install 18c instead.

Any thoughts?

One difference I have noticed with 19c, over 12.2 or 18c, is in using ASM Filter Driver. When you do 'asmcmd afd_label label_name /dev/nvme10n1p1, on 12.2 or 18c, it takes *forever*....up to a minute or more, in my case. No errors, and it does work fine, it's just exceedingly slow. In 19c, I get sub-second response time. I haven' drilled down to see what's going on, I'm just happy it's resolved in 19c.

Again, this is on Linux.

I would go with 19c just because you can stay on it a little longer. However, my experience is Linux. I havent done GI on AIX since 10gR2.

We went through a similar upgrade. 19c is the way to go as it's the long-term supported version (think 11.2.0.4). If you are using Linux, you'll need version 7 or higher to use 19c.

See the My Oracle Support document, Release Schedule of Current Database Releases (Doc ID 742060.1)

So we are heading towards migrating our current environment which is on the primitive version of 11.2.0.3. My personal idea is to upgrade to one of the latest versions of Grid Infrastructure. Either 18c or 19c.

As per your knowledge, experience and observation, which GI version is more stable?

One thing to keep in mind (a possible complication) is that the app vendor is not ready for database higher than ver 12.1.0.2. Which means whatever GI version we proceed with, the DB will still be 12.1

Suggestions please!

Thanks.
